## Timestamp[​](#timestamp "Direct link to Timestamp")

If you need to specify a timestamp for the migration name, use the `-t` (alias for `--timestamp`) and pass the timestamp (should be a non-negative number)

```
typeorm -t <specific-timestamp> migration:{create|generate}
```

You can get a timestamp from:

```
Date.now()

/* OR */ new Date().getTime()
```
